Efficiency and power upgrade at the aged lignite-fired power plant by flue gas waste heat utilization: High pressure versus low pressure economizer installation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A substantial potential exists for the recovery of flue gas waste heat at aged coal-fired power plants. High and low pressure economizers (HPE, LPE) can be applied for this purpose. Two cases of the feedwater supply to the ...
Radionuclide Immobilization by Sorption onto Waste Concrete and Bricks-Experimental Design Methodology
(Springer International Publishing Ag, Cham, 2019)
The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that ...
The Effect of Vanadium Content on Microstructure and Impact Toughness of Forged High Alloy Steel X96CrMo12-1
(Springer International Publishing Ag, Cham, 2019)
The aim of this research was to examine the influence of vanadium on the structure and impact toughness of the forged high alloy steel X96CrMo12-1. It is known that vanadium affects the process of solidification of this ...
Possibilities for wider investment in solar energy implementation
(Pergamon-Elsevier Science Ltd, Oxford, 2019)

Characterisation of undermatch welded joint of X20CrMoV121 steel after prolonged service
(Belgrade : DIVK, 2014)
Heat resistant martensitic steel X20CrMoV121 (DIN) is extensively used in the last few decades as a material for tubing systems and pipelines in thermal power plants. Long term behaviour of this material is well known and ...
Fatigue Life Estimation of Notched Structural Components
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2010)
This work considers the analytical/numerical methods and procedures for obtaining the stress intensity factors and for predicting the fatigue crack growth life of notched structural components. Many efforts have been made ...
Sustainable sub-geothermal heat pump heating in Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Considering the necessity of improvement of Serbian energy production structure through higher participation of clean and renewable energy sources, the possibility of utilization of low enthalpy geothermal waters have been ...
Estimation of the number of trays for natural gas triethylene glycol dehydration column
(Elsevier, Amsterdam, 2011)
The paper deals with the tray-to-tray method for determining the required number of trays in columns with intensive entrainment of liquid when the operating line of the "dry working regime" is not straight and with a small ...
Groundwater heat pump selection for high temperature heating retrofit
(Elsevier Science Sa, Lausanne, 2012)
Retrofitting of fossil fuel powered hot water radiator heating systems of the existing buildings by groundwater heat pumps can provide significant energy savings followed by economic and environmental benefits. The paper ...
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIO-MOL 490 K. welded by MAC (CO2) welding method. ...
